Twisted Wing Flow Dividing Valve for Toy Gun Frost Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flow dividing valves in toy guns experience hindrance due to frost formation in the gas chamber, caused by heat absorption of fuel gas, leading to reduced smooth operation and hindered movement.
Innovation Solution
A flow dividing valve structure featuring a rotating auxiliary portion with twisted wing portions and a concave groove design, allowing frost removal through gas flow and enhanced gas sealing, enabling smooth piston reset and bullet propulsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional flow dividing valve is used to push the air cylinder for bolt reset, then the bolt reset action can be achieved, but frost will be generated in the gas chamber due to heat absorption during gasification, causing the flow dividing valve to be hindered and unable to move smoothly
Solution Approach 1:
The flow dividing valve is designed with twisted wing portions that enable it to rotate dynamically within the gas chamber. This rotational movement allows the valve to actively remove frost by disrupting frost accumulation on chamber walls, thereby maintaining smooth operation despite the cold environment created by gasification heat absorption
Solution Approach 2:
The patent converts the harmful effect of frost formation (caused by heat absorption during gasification) into a beneficial function. The frost removal mechanism uses the same gas flow that causes frosting to rotate the valve, which then actively clears frost from the chamber walls, turning the harmful frosting effect into a self-cleaning mechanism
2Reliability
If the flow dividing valve is designed with twisted wing portions to rotate and remove frost, then frost removal capability is improved, but the device complexity increases
Solution Approach 1:
The flow dividing valve is designed to perform multiple functions simultaneously: it divides gas flow to push the air cylinder for bolt reset, and its twisted wing portions enable it to rotate and remove frost from the gas chamber walls. By combining these functions into a single component, the patent avoids adding separate frost removal mechanisms, thereby limiting the increase in device complexity
3Reliability
If gas is gathered through the concave groove portion design, then gas chamber sealing is improved, but the device complexity increases
Solution Approach 1:
The concave groove portions are strategically positioned on specific surfaces of the flow dividing valve to create localized gas gathering zones. This local modification of the valve geometry enhances sealing at critical interfaces without requiring a complete redesign of the entire valve structure, thereby limiting the increase in device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively removes frost, ensures smooth operation by rotating the valve, enhances gas sealing, and allows complete piston reset with insufficient gas, stabilizing bullet speed through eddy current generation.
Implementation Method 1
high pressure gas will be in contact with the twisted faces when guided in through the flow dividing hole to drive the whole flow dividing valve to rotate, thereby removing the frost from the gas chamber
Implementation Method 2
eddy current will be yielded because of the rotation of the flow dividing valve, allowing the pressurized gas to push a bullet forward so as to stabilize a bullet speed
Implementation Method 3
fuel gas will absorb heat upon gasification, which causes frost to be generated in a gas chamber

AI summary
A flow dividing valve structure for a toy gun includes: a propulsion portion; a rotating auxiliary portion extended from one face of the propulsion portion; and a latching portion, configured on one end of the rotating auxiliary portion far away from the propulsion portion, where the rotating auxiliary portion is configured with a plurality of wing portions each twisted toward a direction away from the propulsion portion so as to be allowed to have at least one twisted face. Whereby, high pressure gas will drive the rotating auxiliary portion to rotate through the wing portions when flowing through the rotating auxiliary portion, and further remove the frost generated inside a gas chamber so as to prevent the unsmooth operation of the flow dividing valve.
